Bakery products, as an important part of a healthy diet, are characterized by their limited shelf-life. Microbiological spoilage of these products not only affects the quality characteristics and result in the economic loss but also threatens consumer's health. Incorporation of chemical preservatives, as one of the most conventional preserving techniques, lost its popularity due to the increasing consumer's health awareness. Therefore, the bakery industry is seeking alternatives to harmful antimicrobial agents that can be accepted by health-conscious customers. In this regard, essential oils have been previously used as either a part of product ingredient or a part of the packaging system. Therefore, the antimicrobial aspect of essential oils and their ability in delaying the microbiological spoilage of bakery products have been reviewed. Several types of essential oils, including thyme, cinnamon, oregano, and lemongrass, can inhibit the growth of harmful microorganisms in bakery products, resulting in a product with extended shelf-life and enhanced safety. Research revealed that several bioactive compounds are involved in the antimicrobial activity of essential oils. However, some limitations, such as the possible negative effects of essential oils on sensory parameters, may limit their applications, especially in high concentrations. In this case, they can be used in combination with other preservation techniques such as using appropriate packaging materials. Further research regarding the commercial production of the bakery products formulated with essential oils is required in this area.

精油作为烘焙产品的天然防腐剂:了解其作用机理,最新发现和应用。

面包产品作为健康饮食的重要组成部分,其保质期有限。这些产品的微生物变质不仅影响质量特性并导致经济损失,而且还威胁到消费者的健康。作为最传统的防腐技术之一,化学防腐剂的掺入由于消费者对健康的意识增强而失去了普及。因此,烘焙业正在寻求健康意识强的客户可以接受的有害抗微生物剂的替代品。在这方面,以前已经将精油用作产品成分的一部分或包装系统的一部分。因此,综述了香精油的抗菌性及其延缓烘焙产品微生物变质的能力。百里香,肉桂,牛至和柠檬草等几种香精油可以抑制烘焙产品中有害微生物的生长,从而延长产品的保质期并提高其安全性。研究表明,几种生物活性化合物与精油的抗菌活性有关。但是,某些限制(例如精油可能对感觉参数产生负面影响)可能会限制其应用,尤其是在高浓度下。在这种情况下,它们可以与其他保存技术结合使用,例如使用适当的包装材料。在该领域中,需要对商业化生产用精油配制的烘焙产品进行进一步的研究。可以抑制烘焙产品中有害微生物的生长,从而延长产品的保质期并提高安全性。研究表明,几种生物活性化合物与精油的抗菌活性有关。但是,某些限制(例如精油可能对感觉参数产生负面影响)可能会限制其应用,尤其是在高浓度下。在这种情况下,它们可以与其他保存技术结合使用,例如使用适当的包装材料。在该领域中,需要对商业化生产用精油配制的烘焙产品进行进一步的研究。可以抑制烘焙产品中有害微生物的生长,从而延长产品的保质期并提高安全性。研究表明,几种生物活性化合物与精油的抗菌活性有关。但是,某些限制(例如精油可能对感觉参数产生负面影响)可能会限制其应用,尤其是在高浓度下。在这种情况下,它们可以与其他保存技术结合使用,例如使用适当的包装材料。在该领域中,需要对商业化生产用精油配制的烘焙产品进行进一步的研究。研究表明,几种生物活性化合物与精油的抗菌活性有关。但是,某些限制(例如精油可能对感觉参数产生负面影响)可能会限制其应用,尤其是在高浓度下。在这种情况下,它们可以与其他保存技术结合使用,例如使用适当的包装材料。在该领域中,需要对商业化生产用精油配制的烘焙产品进行进一步的研究。研究表明,几种生物活性化合物与精油的抗菌活性有关。但是,某些限制(例如精油可能对感觉参数产生负面影响)可能会限制其应用,尤其是在高浓度下。在这种情况下,它们可以与其他保存技术结合使用,例如使用适当的包装材料。在该领域中,需要对商业化生产用精油配制的烘焙产品进行进一步的研究。它们可以与其他保存技术结合使用,例如使用适当的包装材料。在该领域中,需要对商业化生产用精油配制的烘焙产品进行进一步的研究。它们可以与其他保存技术结合使用,例如使用适当的包装材料。在该领域中,需要进一步研究以精油配制的烘焙产品的商业化生产。
